Just be grateful you got away before you made a mistake. Nothing worse than waking up during the night after you've bought too much car, and thinking to yourself "**** what did I just do!!!". Been there, done that (many years ago).
And others have pointed out, income level is actually meaningless. Net income is what matters, and if you are burdened by excessive debt, children, wives, ex-wives, etc, $250k/year can disappear in a hurry.
Also... For the same price as that P-car you can have an M3 AND a GT-R... Think about it. It's a great combo.
